I recently beat God of War III, not really sure how I would rank the games. None of them really blew me away as anything too special. I played them pretty far apart from each other so it's hard for me to compare them.
I played the PS2 version of GoW and GoW2, I don't know how much playing the PS3 versions could boost them. I guess I would go 3 > 2 > 1, but I don't know. I'm curious to see what the consensus is.
